Description
Die Erfindung geht von einem Wischarm nach dem Oberbegriff des Anspruchs 1 aus.The invention relates to a wiper arm according to the preamble of claim 1.
Bekannte Scheibenwischer weisen einen Wischarm auf, der auf einer Wischerwelle sitzt. Diese wird von einem Wischermotor angetrieben. Der Wischarm weist am freien Ende seiner Wischstange ein hakenförmiges Ende auf, das in einen Einhängekasten eines Mittelbügels eines Wischblatts greift und ein Lagerteil umfasst, in dem schwenkbar ein Gelenkbolzen des Wischblatts gelagert ist. Das Wischblatt besitzt in der Regel ein mehrgliederiges Tragbügelsystem mit dem Mittelbügel, an dem untergeordnete Bügel angelenkt sind, von denen zumindest einige mit Krallen an ihren Enden eine Wischleiste halten.Known windscreen wipers have a wiper arm on a wiper shaft sits. This is powered by a wiper motor driven. The wiper arm points at the free end of its wiper rod a hook-shaped end that fits into a hanging box a middle bracket of a wiper blade attacks and a bearing part comprises, in which pivotally a hinge pin of the Wischblatts is stored. The wiper blade usually has a mehrgliediges carrying handle system with the center bracket, on are hinged to the subordinate bracket, of which at least Some with claws at their ends a wiper strip hold.
Es sind auch gelenklose Wischblätter bekannt, die anstelle des Tragbügelsystems ein senkrecht zur Fahrzeugscheibe federndes, elastisches Tragelement besitzen, das aus Kunststoff hergestellt ist. Um die Federeigenschaft zu verbessern, kann es mindestens eine Federschiene aus Federstahl aufweisen. Das Tragelement besitzt im unbelasteten Zustand eine stärkere Krümmung als die Fahrzeugscheibe, so dass sich die Wischleiste unter der Anpresskraft des Wischarms mit einer geeigneten Druckverteilung an die Fahrzeugscheibe anlegt.There are also known jointless wiper blades, instead of the mounting bracket system is a resilient perpendicular to the vehicle window, possess elastic support element, made of plastic is made. To improve the spring characteristic, can have at least one spring rail made of spring steel. The Support element has a stronger in the unloaded state Curvature as the vehicle window, leaving the wiper strip under the contact force of the wiper arm with a suitable Apply pressure distribution to the vehicle window.
Gelenklose Wischblätter bauen sehr niedrig, was bezüglich ihres strömungstechnischen Verhaltens und der Geräuschentwicklung im Fahrtwind sehr günstig ist. Aus der DE 199 24 662 A1 ist ein Scheibenwischer mit einem gelenklosen Wischblatt bekannt, das über ein so genanntes "Sidelock-System" an einem Wischarm angelenkt ist. Hierzu ist ein Stift an dem freien Ende des Wischarms, der ein zur Fahrzeugscheibe hin offenes, u-förmiges Profil aufweist, seitlich und quer zu dessen Längsrichtung und zu dem Wischblatt zeigend vernietet. Der Stift ist in einer Lagerbohrung eines Verbindungsteils schwenkbar gelagert, welches fest mit dem Tragelement des Wischblatts verbunden ist.Artless wiper blades build very low, which in terms of their fluidic behavior and noise in the wind is very cheap. From DE 199 24 662 A1 is a windshield wiper with a jointless wiper blade known the so-called "sidelock system" on one Wischarm is articulated. This is a pin on the free End of the wiper arm, which opens to the vehicle window, U-shaped profile, laterally and transversely to the Riveted longitudinal direction and pointing to the wiper blade. Of the Pin is in a bearing bore of a connecting part pivotally mounted, which is fixed to the support element of the Wischblatts is connected.
Parallel zum Stift ist am Wischarm in Längsrichtung versetzt eine Brücke angeordnet, die an ihrem freien Ende zur Seite des Stifts hin abgewinkelt ist. In einer Montageposition, in der das Wischblatt quer zur Längsrichtung des Wischarms gehalten wird, kann der Stift in die Lagerbohrung des Verbindungsteils geschoben werden. Wird das Wischblatt anschließend parallel zur Längsrichtung des Wischarms gedreht, übergreift die Brücke das Wischblatt und verriegelt es mit ihrem abgewinkelten Ende, so dass das Wischblatt im montierten Zustand auf dem Stift zwischen dem abgewinkelten Ende der Brücke und dem Wischarm geführt ist. Die Brücke taucht in der Betriebsstellung des Wischblatts in eine entsprechende Nut des Verbindungsteils ein und schließt etwa bündig mit der Oberseite des Verbindungsteils ab. Zur Demontage muss das Wischblatt in die entgegengesetzte Richtung geschwenkt werden, bis das abgewinkelte Ende außer Eingriff gebracht ist und das Wischblatt vom Stift gezogen werden kann.Parallel to the pin is offset on the wiper arm in the longitudinal direction a bridge arranged at its free end to the side angled out of the pen. In a mounting position, in the wiper blade held transversely to the longitudinal direction of the wiper arm is, the pin in the bearing bore of the connecting part be pushed. Will the wiper blade subsequently rotated parallel to the longitudinal direction of the wiper arm, overlaps the bridge wipes the blade and locks it with its angled End, leaving the wiper blade in the assembled state on the pin between the angled end of the bridge and guided the wiper arm. The bridge appears in the operating position of the wiper blade in a corresponding groove of the connecting part and closes approximately flush with the top of the connecting part. For disassembly, the wiper blade must be in the opposite direction will be panned until the angled End is disengaged and that Wiper blade can be pulled from the pen.
Des Weiteren zeigt das Dokument US-A-5 618 124 einen Wischarm mit einem seitlichen, zu einem Wischblatt zeigenden Stift, der als Befestigungsmittel zur Befestigung des Wischblattes dient. Der Stift ist an einem Adapter angeordnet, der in ein hakenförmiges Ende des Wischarms mittels einer Klippverbindung eingesetzt.Furthermore, document US-A-5 618 124 shows a wiper arm with a lateral, pointing to a wiper blade pin, which serves as a fastener for Attachment of the wiper blade is used. The pin is placed on an adapter inserted into a hook-shaped end of the wiper arm by means of a clip connection.
Nach der Erfindung hat die Wischstange des Wischarms ein hakenförmiges Ende, wie es allgemein üblich ist, jedoch nicht für Sidelock-Systeme verwendet wird. Damit solche weit verbreiteten Wischarme auch für Wischblätter geeignet sind, die mit einem Sidelock-System gelenkig mit dem Wischarm verbunden werden, ist in das hakenförmige Ende ein quer zum Stift geteilter Adapter eingesetzt, mit dem der Stift verbunden ist. Die Adapterteile besitzen nach innen weisende Passstücke, an die sich nach außen Flansche anschließen, die seitlich am hakenförmigen Ende anliegen. Die Adapterteile werden bei der Montage vorzugsweise lösbar miteinander verbunden und in Längsrichtung am hakenförmigen Ende fixiert. Die Brücke ist mit einem der Adapterteile fest verbunden.According to the invention, the wiper rod of the wiper arm has a hook-shaped End, as is common practice, but not used for sidelock systems. Thus, such widespread Wiper arms are also suitable for wiper blades, the articulated to the wiper arm with a sidelock system be, is divided into the hook-shaped end a transverse to the pen Adapter used, with which the pin is connected. The adapter parts have inwardly facing fittings on which connect to the outside flanges, the side of the hook-shaped End lie. The adapter parts are at the Assembly preferably releasably connected to each other and in Fixed longitudinally on the hook-shaped end. The bridge is firmly connected to one of the adapter parts.
Durch den in das hakenförmige Ende der Wischstange eingesetzte Adapter erfüllt der erfindungsgemäße Wischarm alle Anforderungen für ein Sidelock-System. Er kann mit wenigen Handgriffen umgerüstet werden, so dass er sowohl für übliche Wischblätter mit einem Tragbügelsystem als auch für gelenklose Wischblätter geeignet ist, die in der Regel eine Verbindung nach dem Sidelock-System erfordern, um die Vorteile einer geringen Bauhöhe nutzen zu können. Ein weiterer Vorteil besteht darin, dass die Form und die Abmessung des gelenklosen Wischblatts und des Wischarms mit dem hakenförmigen Ende erhalten bleiben und keine konstruktiven Veränderungen bzw. neue Werkzeuge zum Fertigen dieser Bauteile notwendig sind.By inserted into the hook-shaped end of the wiper rod Adapter wiper arm of the invention meets all requirements for a sidelock system. He can in a few steps be retooled so that it is both standard Wiper blades with a carrying handle system as well as for hingeless Wiper blades is suitable, which is usually a connection after the sidelock system require the benefits of a to use low height. Another advantage is that the shape and the dimension of the jointless Wiper blade and the wiper arm with the hook-shaped end be preserved and no constructive changes or new tools for manufacturing these components are necessary.
Die Adapterteile können durch jede geeignete Verbindungstechnik, z.B. durch Kleben, Klippsen oder Nieten, miteinander verbunden werden. Eine zuverlässige und leicht lösbare Verbindung erreicht man durch eine Schraube, so dass der montierte Adapter jederzeit wieder entfernt und etwa ein Wischblatt mit einem Tragbügelsystem angelenkt werden kann.The adapter parts can be replaced by any suitable connection technique, e.g. by gluing, clipping or riveting together get connected. A reliable and easily detachable connection one reaches by a screw, so that the mounted Adapter removed again at any time and about one Wiper blade can be hinged with a mounting bracket system.
Die Schraube, die zweckmäßigerweise eine Senkschraube ist, wird durch ein Schraubenloch des einen Adapterteils gesteckt und in ein Gewindeloch des anderen Adapterteils eingeschraubt. Vor dem Zusammenschrauben werden die Adapterteile zweckmäßigerweise durch Zentriermittel, z.B. eine Fügenut und eine entsprechende Passfeder an den Passstücken, gegeneinander zentriert. Beim Anzug der Schraube werden die Flansche gegen die Seiten des hakenförmigen Endes verspannt und in axialer Richtung in vorteilhafter. Weise durch einen Nocken gesichert, der an einem Flansch angeformt ist und sich außen zumindest teilweise über den gebogenen Teil des hakenförmigen Endes erstreckt. Zum Sichern können auch Rastmittel verwendet werden, z.B. Rastnasen, die in Rastvertiefungen des Gegenstücks eingreifen.The screw, which is expediently a countersunk screw, is inserted through a screw hole of one adapter part and screwed into a threaded hole of the other adapter part. Before screwing together, the adapter parts expediently by centering means, e.g. a joining groove and a corresponding key on the fitting pieces, against each other centered. When tightening the screw, the flanges become clamped against the sides of the hook-shaped end and in axial direction in an advantageous. Way through a cam secured, which is formed on a flange and on the outside at least partially over the curved part of the hook-shaped Endings extends. Locking devices can also be used for securing be, e.g. Snap-in lugs in the locking recesses of the counterpart intervention.
Um den Stift mit der Wischstange zu verbinden, besitzt eines der Adapterteile ein Stiftloch, das zweckmäßigerweise als eine gestufte Sackbohrung ausgebildet ist. In dieses Stiftloch wird der Stift mit einem Ende eingesetzt, bis ein Bund, der an diesem Ende des Stifts vorgesehen ist, an einer Anlagefläche des abgesetzten Stiftlochs anliegt. Im anderen Adapterteil ist eine Passbohrung vorgesehen, die vom anderen Ende über den Stift gepresst wird, bis eine entsprechende Anlagefläche an dem Bund des Stifts anliegt. Somit ist der Stift nach der Montage des Adapterteils spielfrei im Adapter gehalten, der wiederum über seine Passstücke spielfrei im hakenförmigen Ende der Wischstange befestigt ist. Grundsätzlich kann das Stiftloch wie die Passbohrung mit einer Presspassung dimensioniert werden. Wird jedoch nur die Passbohrung mit einer Presspassung versehen, ist es wegen der Abstützverhältnisse günstig, wenn die Passbohrung in dem Adapterteil vorgesehen wird, das dem Wischblatt zugewandt ist. An diesem Adapterteil wird auch zweckmäßigerweise die Brücke mit ihrem abgewinkelten Ende angeformt.To connect the pin with the wiper rod, has one the adapter parts a pin hole, which expediently as a stepped blind bore is formed. In this pin hole The pin is inserted with one end until a collar, the is provided at this end of the pin, on a contact surface abuts the remote pin hole. In the other adapter part a fitting hole is provided from the other end is pressed over the pin until a corresponding contact surface attached to the covenant of the congregation. Thus, the pen held in the adapter without clearance after assembly of the adapter part, in turn, via his fittings in the hook-shaped play End of the wiper rod is attached. in principle The pin hole can be like the mating hole with a press fit be dimensioned. But only the fitting hole with a Press fit provided, it is because of the support conditions favorable if the fitting bore provided in the adapter part which faces the wiper blade. At this adapter part is also conveniently the bridge with its angled End molded.
Grundsätzlich können die Adapterteile mit der angeformten Brücke, der Stift und die Schraube aus Kunststoff hergestellt werden. Aus Festigkeitsgründen kann es jedoch zweckmäßig sein, den Stift und die Schraube aus Metall zu fertigen, wobei die Adapterteile aus Kunststoff die Metallteile gegeneinander isolieren, und zwar den Stift und die Schraube einerseits und die Wischstange andererseits.Basically, the adapter parts with the molded Bridge, the pin and the screw made of plastic become. For reasons of strength, however, it may be appropriate be to manufacture the pin and the screw of metal, wherein the adapter parts made of plastic, the metal parts against each other isolate, the pin and the screw on the one hand and the wiper rod on the other hand.
